We want to model this as an analysis and make following changes. - Rename LoopMemDepAnalysis as DataDependenceAnalysis. Various transformation passes will use this interface to access data dependence info. This is an external interface. Put this in include/ llvm/Analysis. - Make DirectionVector (and later on DistanceVector) independent interface and put them in ADT. - Put various tests, DeltaTest, in lib/Ana...

...ually not be implemented as a separate Analysis but placed into Support. For instance, DeltaTest would use GCD or other tests on a different set of indexes once constraints are propagated. This means these tests are called on expressions that are not necessarily present in the code itself. > - DataDependenceAnalysis will select various dependence tests based > on > user selection.

That will probably be the most difficult part. Bu...

Sure. For now, I am posting it as an attachment, because it does not build against the current SVN version. It is really basic (for example, it cannot produce distance vectors,

Wojtek, Please see David's message below. Have you or can you check in your code, perhaps as a project for now? That will allow us to start looking at it and perhaps collaborating on it. --Vikram Associate Professor, Computer Science University of Illinois at Urbana-Champaign http://llvm.org/~vadve On Aug 20, 2008, at 3:05 PM, David Greene wrote: > On Wednesday 20 August 2008
